I need advice...

I actually went on a date tonight with a guy I didn't know very well. I have been sick most of the week, and I did not feel very well on the date either, but hated to stand him up. We were able to have a decent conversation, but he didn't "knock my socks off." I always wonder in these situations how long of a chance should I give it? Another date or two? Should I just trust my intuition and call it off now? Would things have gone better for me if I hadn't felt sick?

I just really hate hurting people's feelings. And yet, there are also people in my life that grew on me over time, which is why we are all friends now.
